What is shea butter? Benefits & Uses

updated on 06/12/2026

Shea butter is a natural fat extracted from the kernels of the Vitellaria paradoxa tree, a wild-growing tree found in the sub-Saharan shea belt of West Africa. Packed with fatty acids, vitamins and anti-inflammatory compounds, it has been used for centuries to protect, hydrate and heal the skin. Today, it is one of the most studied natural skin care ingredients out there, and clinical research supports what West African communities have known for generations.

Where does shea butter come from?

Shea (Vitellaria paradoxa) is remarkable in its own right. These trees live up to 300 years and do not produce fruit until 15 to 20 years after they begin to grow. In much of West Africa, they are considered sacred and are never intentionally cut. The fruit, which looks like a small plum, ripens and falls between May and July. The women pick the fallen fruits by hand, open the outer shell and extract the inner kernel. These kernels are dried, roasted, ground and churned using traditional methods to separate the fat.

The result is raw, raw shea butter in its most natural state. Most of the shea butter sold in the United States comes from Ghana, Burkina Faso, Mali, and Nigeria. The industry supports hundreds of thousands of women across the shea belt, making it one of the most economically important agricultural products in sub-Saharan Africa.

What’s in Shea Butter?

The reason shea butter works so well on the skin is because of its chemistry. Its fatty acid profile closely mirrors the lipid structure of healthy human skin, so it is easily absorbed without disturbing the skin’s natural balance.

These compounds do not work in isolation. Fatty acids transport vitamins to the skin, triterpenes soothe any inflammatory reaction, and ceramides help seal in moisture once it’s there.

What Does Science Say?

The anecdotal case for shea butter stretches back centuries. The clinical case is steadily developing, and the recent results are sufficiently specific to merit immediate mention.

A 2025 study published in International Journal of Pharmaceutical and Organic Chemistry measured the effects of shea butter on skin barrier function using standardized methods such as Trans-Epithelial Water Loss (TEWL) measurement, keratometry, and impedance spectroscopy. Results showed that TEWL decreased by 37.8% after 24 hours, skin hydration increased by 58% after 24 hours, and impedance spectroscopy showed a 33% increase in skin resistance, indicating improved barrier function. The same analysis confirmed six subclasses of ceramides present in shea butter, with Ceramide 1 and 2 being the most abundant. These are the same lipids that the skin uses to seal and repair its protective layer.

Separate research in the triterpene ester fraction supports the anti-inflammatory effect of shea butter. The anti-inflammatory and protease inhibitory activity of triterpene esters has been reported and reviewed in the literature, indicating the potential to reduce skin stress caused by environmental factors.

This is part of why shea butter is consistently recommended for eczema and psoriasis. Both conditions involve a disrupted skin barrier and persistent inflammation. Shea butter addresses both at the same time.

Unrefined vs. Refined Shea Butter

Not all shea butter is the same. The processing method determines how much of this nutrient profile actually reaches your skin.

Unprocessed vs. Enhanced Comparison Table

Raw shea butter is processed without chemical solvents or high heat, maintaining its full nutritional profile. Unprocessed shea retains over 90% of its natural nutrients, including vitamins A and E, essential fatty acids, and therapeutic compounds such as cinnamic acid esters that provide anti-inflammatory benefits.

Refined shea butter goes through additional steps to create a white, odorless product more practical for large-scale cosmetic production. The refining process (if not naturally refined), can often include hexane and bleach to remove color and odor, can result in the loss of up to 75% of the bioactive compounds that make shea butter valuable for skin care.

Note on Labeling: “Raw” and “unprocessed” mean the same thing in this context. If a product is authentically raw, it will have a natural ivory or pale yellow color and a mild aroma. Bright white and odorless means it has been refined, regardless of what the label claims.

Better Shea Butter sells 100% unprocessed organic shea butter, sourced and processed to maintain full nutrient content.

What skin benefits does shea butter offer?

Because its fatty acid profile mirrors the lipid structure of the skin, shea butter works on a wide range of problems rather than targeting one. Regular use supports moisture retention, barrier repair and inflammation reduction. Commonly used for eczema, psoriasis, acne-prone skin, stretch marks, minimal wound healing and signs of aging. It also works on the hair and scalp.

How to choose quality shea butter

Color one thing to look for. True raw shea is ivory to pale yellow. Green or gray tones indicate early season harvest, which is nice and still rich in nutrients. Bright white indicates chemical treatment.

The aroma confirms it. Unprocessed shea has a mild, slightly smoky, nutty smell. No fragrance at all means it has been deodorized.

The texture should be solid at room temperature and melt quickly on contact with the skin. Granules can develop if the butter melted and resolidified during shipping. This does not affect the quality. Gently melting the butter in a double boiler over low heat and quickly chilling it in the refrigerator or freezer usually restores softness.

Third-party certifications provide an additional level of trust. USDA Organic certification means the trees and processing meet both certified organic standards.
